ADJUSTABLE FLANGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 487,331, dated December 6, 1892.

Application filed October 4:, 1892. Serial No. 447,861. (No model.)

To all whom it may concern.-

Be it known that I, JULIUs W. KELLAM, a citizen of the United States, residing at the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Adjustable Flange- Wrenches, of which the following is a specification. l

My invention relates to that class of tools or devices employed for screwing on or off the flanges used in gas, water, and steam pipe fitting, the.; and the objects of my improvements are to provide a simple effective tool for such purposes which shall be expeditiously, safely, andconveniently used, not liable to easy derangement, and at the same time shall have a rangeof adjustment sufficient to accommodate several sizes of iianges. I attain these objects by'means of the mechanism and devices illustrated in the accompanying drawings, in whioh- Figure l is a front elevation of my inven` tion, partly sectional, showing Vthe construe-l tion, application, and operation of the saine.; and Fig. 2 isa side elevation, partly sectional, as the same would appear looking from the right hand to the left of Fig. 1,*further showing construction and operation of parts of my invention more in detail, all of which will be more fully described hereinafter.

Like letters indicate corresponding parts throughout the respective figures.

A is lever-bar of iron or other suitable metal.

B is a double right-angled integral swiveljaw pivoted to the bar A by the bolt O and provided with alip ct of corresponding rightangular form secured by rivets or screws b b.

D is a duo-formed dog mortised vertically in the manner shown and fitted to slide freely up and down the fiattened wider portion of the bar A.

E is a disk of hardened steel resting in a socket c in the dog, one side of which is roughened, as seen at d, for engagement with a similarly-roughened surface e on one side of the bar, and the rear side of which is in j uxtaposition with a set-screw f, by which it may be forced against the roughened surface e on the 5o bar A to prevent the dog from slipping when the tool is being used.

7L o are precisely-similar biting-edges of the dog arranged in the same vplane with the swivel-jaw B. The object of the two bitingedges 71, h will more fully appear hereinafter.l

F is the rounded handle end of thelever A.

The dotted outlines of the bar A and the dog D in Fig. l shows the manner of adjusting my invention to unscrew a flange.

H is a liange with threaded opening i and bolt-holes jjj in the rim, and I is the threaded end of a section of pipe upon which the liange H is screwed. v

lt k' are short pins projecting on one side of the lever-bar A to answer as stops to prevent the dog D from sliding too far upward 0r downward thereon.

L in Fig. 2 illustrates one means of providing an extension of the lever-handle F. It will be seen that the bar A extends across the face or front of the flange IALforming a straightlilvnle I connection between the swivel-jaw B and the"d`og D. Itwill also be noticed that opposite faces of the swivel-jaw B-are provided with serrations or teeth of precisely-similar form but reverse in direction of pitch. This j aw B is made of hardened steel. l

The operation of my invention is as follows: An internally-threaded liange is started upon the threaded end of a suitably-sized pipe. The workman now places the Wrench in the position shown, with the swivel-jaw astride of the rim of the flange and so that the lip a, is beyond the same, as seen in Fig. l. He now unscrews the setscrew f, which releases the disk E from frictional contact with the roughened surface e on the bar and allows the dog to he moved into a position relatively right for engagement with the harige-rim, which is now done. He now tilts the dog D to the position shown in the full-line drawingFig.1,with the right-hand biting edge of the same presented to the iiange, and then screws the setscrew f down against the disk E hard, which causes the latter to engage firmly with the roughened surface of the bar A and to be rigidly held in position thereon. Vith the hands he now grasps the lever F and pulls in the direction of the arrow, which causes the biting edge of the dog to take hold of the flangerim and impinge the flange between the dog and the swivel right-angular jaw B, so that IOO there cannot be, any slip,`tl,ll1s screwing the flange apen, the pipe. N ow by peeping ipe lever-handle backward again to the position rst started from a new bite is obtained upon the ange-rim and a forward pull then further Screws the danse ori- Danna these opera,- tions the lip a, overhanging the rim, as seen in Fig. 1, keeps the Wrench from slipping to, one side and off.

When it is required to use the tool for nn; screwing a flange, the workman proceeds as before, except he puts the lever in the position shown by the, dotted outlines of the, eene,

'bination of a lever-bar extended across the in Fig. 1 and tilts the dog D in the opposite direction, so that the opposite biting. edge. of the latter Will be in Contact with the flangefial-A Tiaep by pail-ipe or puppies the, Leveriiapdfle in the other direotiofa' the danse afi-1,1 be aaeorewed,
